Untethered holidays

Untethered holidays

@pod2g has created a terrific gift for iOS fans — an untethered 5.0.1 jailbreak for non-A5 devices!

Many of you have already been following @pod2g’s blog where he’s been keeping everyone up to date on his progress. And so you know that he recently decided to push the button on a release for all devices except the new iPhone4S and iPad2. @pod2g’s untether involves two separate exploits and a few other “tricks” — and since he’s taken the @comex approach of doing nearly everything himself, you know his plate has been full these past few months!

A few days ago, @pod2g gave the untether to both the iPhone devteam and the chronic devteam. We’ve put it into redsn0w 0.9.10 and PwnageTool, and the chronic devteam put it into a Cydia package (the same set of exploits is in all three).

Here are the basic steps for how to get it:

The untether is for iOS 5.0.1 on iPhone3GS, iPhone4, iPhone4-CDMA, iPad1, iPod touch 3G, iPod touch 4G
If you have one of those devices and are not on 5.0.1 yet, update now! The SHSH window is still open for 5.0.1 If you unlock via ultrasn0w or gevey, make sure you only get to 5.0.1 via a custom IPSW! See the guides at places like iClarified.com if you don’t know how. Once you’re at 5.0.1, use the latest redsn0w 0.9.10 to both jailbreak and untether.
If you’re already at 5.0.1 with a tethered jailbreak, you have two choices: either run redsn0w 0.9.10 over your current jailbreak (deselect “Install Cydia” if you do that), or install the Cydia package prepared by the chronic devteam. The patches are the same regardless of which you choose.
Some of you are using a hybrid 5.0/5.0.1 configuration. If so, do not attempt to install this untether over that setup! You will most likely get into a reboot cycle. Do a sync and fresh restore to 5.0.1 then install the jailbreak + untether.

As mentioned earlier, @pod2g has spent months working on all the exploits and tricks in this untether, and many of you may be wondering how you can send donations. Although the iPhone devteam itself doesn’t take donations, we thought it was appropriate to provide a link at the end of the redsn0w run for you to more easily donate directly to @pod2g if you wish (alternatively, you can go right here). There’s a link in the Cydia package for donating to the chronic devteam for the Cydia version of @pod2g’s untether.

@pod2g is now looking for a way to extend this to A5 devices. Because those devices cannot use geohot’s limera1n exploit to inject the untether, they require exploits above and beyond those used for this release. Keep following pod2g on twitter or his blog for any progress reports!

A5 Jailbreak for iPhone 4S and iPad 2 Has Been Released!!!

The 'Dream Team' of hackers have just released their untethered jailbreak for the iPhone 4S and the iPad 2.

P0sixninja details some of the background in a post on the Greenpoison blog:

The ridiculously complex combination of exploits-within-exploits that make this iOS jailbreak possible have consumed thousands of hours of brain-power & effort from a legion of world-renowned hackers, several of whom have been working diligently on this project since the dual-core A5 processor was unveiled by Apple last March. Ten months ago, I myself was live tweeting from a tediously long line at the nearest Apple retail store, where I anxiously waited to become one of the world's first owners (& hackers) of the newly-released iPad 2.

Despite new tools to help with finding exploits they realized a team effort was necessary.

We finally admitted that the escalated obstacles presented by Apple's new A5 processor would not likely be overcome by one individual or team – but all together, we should be more than able to conquer any challenges encountered. As such, a diverse group of iOS hackers all decided to set aside our personal goals & egos, relax our die-hard team loyalties, and pool our respective skill-sets, talents & exploits to form an iOS Super-Hacking "Dream Team."
